Let's start

Question - The length of a rectangle is twice its breadth. If the perimeter is 72 metre, find the length and breadth of the rectangle.

Answer - Let the breadth of the rectangle be x,

Then the length of the rectangle = 2x

Perimeter of the rectangle = 72

Therefore, according to the question

2(x + 2x) = 72

2 × 3x = 72

6x = 72

x = 72/6

x = 12

We know, length of the rectangle = 2x

= 2 × 12 = 24

Therefore, length of the rectangle is 24 m and breadth of the rectangle is 12 m.

Answer 2

Answer:

HEY BUDDY...

Step-by-step explanation:

In a rectangle,

Let the breadth be b = x

Then length will be l = 2x

Perimeter of rectangle = 2(l+b) = 72m

=> 2(2x + x) = 72

=> 3x=36

=> x = 12

Therefore the length, breadth are l = 2x = 24  ,  b = x = 12

∴  length is 24m and breadth is 12m
